I know a lot of them that I grew up with. Their parents were immigrants, my dad was a immigrant. Lebanon, Iraqis, Iranians, Mexicans. Of course we all still have that pride for the countries our parents came from but ALL of us are pretty much white.
No accent.
We date/marry other ethnicities.
I'm thinking of my buddies asian wife. Her parents may be immigrants but other than the asian face, she's pretty much fully integrated into white culture.
I have a Mexican couple who are citizens now. They feel like they stick out. They feel like people sometimes look at them or treat them differently. They "look" Mexican. But I have a lot of Mexican friends who don't feel that way. I told them if they are getting any grief from anyone, it's probably only after the racist hears their accent.
When you have a good business professional Mexican neighbor, you'll feel a lot different. Or a co worker or friend who's parents happen to come to America from Mexico.
It's the immigrants who stay 100% in their poor ethnic high crime communities. They don't speak to Americans. Their kids are in gangs. They aren't living the American dream No economic opportunities. Growing up in violence.
I notice we don't have a problem in Dearborn MI with all the arabs. Why? Because we didn't cut them off from economic opportunities. In fact we put them in between us and the blacks as a buffer. So we treat foreign born Arab muslims better than we dob blacks who've lived here longer than you.
